Glenn who models in N scale asks:

“My layout is set before the days of mobile phones or underground electrical wiring to houses, so I thought that adding some telephone phones and wires would help authenticate the scene. But then I started to think about the practicality of stringing wires along roads and how they could become a problem if they get snagged. What should I use to replicate the wires? Also, I wondered how far apart to position the poles? Has anyone else worked through these issues? Any guidance in advance would be appreciated. Thank you guys!”
